The story of an expedition into the heart of a mangrove swamp to photograph Flying Foxes. Flying Foxes are large fruit-eating bats They get their name from their clever pointed faces, brilliant eyes, and ever-alert ears. They live in huge colonies and spend the daylight hours hanging upside-down asleep. At sunset they take off in their thousands-flying to feeding grounds that may be twenty miles away and even on islands across the sea.
